Objectives The purpose of this study was to investigate the effects of Silbi-san on the antioxidant and fat accumulation inhibition and to analyze the anti-obesity effect by analyzing the changes in serum lipid composition in obese mice. Methods We compared contents of phytochemicals like total polyphenols and total flavonoid and antioxidant activities such as 2,2-dipheny-1-picrylhydrazyl and 2.2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity. After Silbi-san in 3T3-L1 cells in vitro and mouse adipose tissue ex vivo, we quantified intracellular triglyceride accumulation and lipolysis. Moreover, the anti-obesity activity though inhibiting pancreatic lipase were analyzed. In 3T3-L1 cells, morphological changes showed that control cells had many lipid while cells treated with Silbi-san had less lipid accumulation. 30% EtOH Silbi-san treatment also suppressed the fat absorption by inhibiting the activity of pancreatic lipase and led to high lipolysis through promoting glycerol release. The experimental group was divided into four groups: Normal group fed normal feed, Control group fed 60% high fat diet (HFD) and distilled water, drug group fed 60% high fat diet and 200 mg/kg of Silbi-san water extract, drug group fed 60% HFD and 200 mg/kg of Silbi-san 30% ethanol extract. Results Serum total cholesterol content and serum low density lipoprotein-cholesterol content were significantly decreased in the Silbi-san extract group compared to the control group, serum high density lipoprotein-cholesterol content was significantly increased in Silbi-san extract group. Conclusions In this study, the antioxidant and fat accumulation inhibitory effects of Silbi-san were confirmed.

식품 가공의 부산물 중 동물성 부산물을 재활용하여 조미소재로의 개발 가능성을 탐색하였다. 부산물 원료로는 돼지뼈(PB)와 닭뼈(CB), 그리고 참치 혈합육(TDF)을 사용하였다. PB와 CB를 열수로 18시간 추출한 후 단백질과 지방 분해효소를 처리하여 가수분해물을 제조하였다. 각각의 열수 추출물에서 지방의 제거를 위하여 1차로 lipase활성이 있는 pancreatic enzyme을 처리하고 2차로 Flavourzyme을 사용하는 경우 가수분해도(DH)가 PB는 약 70%, CB는 약 80%까지 증가하였다. 지방이 적은 TDF는 단백질 분해효소인 Alcalase와 Flavourzyme으로 분해한 결과 고형분 회수율은 약 22%, 단백질 회수율은 9%이었으며, 효소분해액 중 유리 아미노산 함량은 고형분 중 27%까지 향상되었다. 세 종류 분해액에 가염한 후 관능적인 특성을 조사한 결과 전체적으로 TDF>PB>CB의 순으로 우수하여 참치 혈합육은 조미소재의 원료로 적합한 동물성 부산물로 판단되었다.

This study examined the antioxidative and lipid accumulation inhibitory effects of 14 plants from Mongolia and Myanmar on 3T3-L1 and HepG2 cells. The total phenolic and flavonoid contents (TPC and TFC) of 14 plant extracts were measured, and the antioxidative activities were analyzed using DPPH, ABTS, FRAP, and ORAC. After measuring the pancreatic lipase levels and performing the thiobarbituric acid assay, the degree of lipid accumulation was determined by lipid (Oil Red O) staining and triglyceride assay in 3T3-L1 and HepG2 cells. M. paniculate (259.43 mgGAE/g) and C. benghalensis (130.78 mgNAE/g) had the highest TPC and TFC, respectively, among the 14 plants. R. acicularis Lindl. had the highest antioxidant activity in DPPH. The ABTS, FRAP, and ORAC results showed that the antioxidant activity of 11 species was higher than that of the positive control. The pancreatic lipase inhibitory effect of C. angustifolium Scop. was reduced to 23.65% at 0.1 mg/mL, and the level of lipid peroxidation of C. abrorescens Lam. was 0.63 nmol/mg. Five selected plants inhibited the lipid accumulation and triglyceride content, respectively, in 3T3-L1 and HepG2 cells. These results provide scientific evidence for developing functional foods using 14 plants from Mongolia and Myanmar, which have antioxidant activities and lipid accumulation reduction effects.

Objectives: This study aimed to compare the anti-obesity effects of raw and pickled garlic in vitro in 3T3-L1 preadipocytes. Methods: The pickled garlic samples comprised the following: garlic aged in vinegar (VG), garlic aged in soy sauce, and vinegar (1:1, v/v) (PG) and raw garlic (RG) as control. Hexane, butanol, and distilled water were used to prepare the fractions. The pancreatic lipase inhibitory activity was used as a measure of anti-obesity effects of the extracts. The lipid droplet accumulation and triglyceride content in the 3T3-L1 cells were measured using Oil red O staining and triglyceride assay kits, respectively. The adipogenesis related protein expression levels were analyzed using the kits and the western blot method. Results: The pancreatic lipase inhibitory activity of the garlic extracts (VG, PG, RG) was the highest in the butanol fraction, and the inhibitory effect was the highest in RG, followed by PG and VG. All garlic butanol extracts suppressed triglyceride accumulation in differentiated adipocytes (P<0.05) through the activation of cyclic adenosine monophosphate (AMP), AMP-activated protein kinase, carnitine palmitoyl transferase-1, and the inhibition of fatty acid synthase. Raw garlic extracts significantly inhibited the expression of proteins involved in adipogenesis as compared to pickled garlic. Conclusions: Raw garlic has the potential to be an effective natural material for reducing obesity compared to pickled garlic with vinegar or soy sauce.

Recently, a major resection of the pancreas has been carried out not only to treat carcinoma of pancreas but also chronic pancreatitis. But limited and often contradictory reports have been made on the exocrine effects after partial surgical pancreatectomy in mammals. It was suggested that the growth of the residual tissue in pancreatectomized rat is very active, because pancreas has the great power of regeneration after partial pancreatectomy, while others observed that rat pancreas after partial surgical resection revealed a perplexing mixture of atrophy and regeneration of acinar tissue. On the other hand, another results showed that the amount of insulin required to control diabetes after partial resection of pancreas is much greater than that needed after total pancreatectomy. Because the anti-insulin system, such as glucagon secretion and hypophyseoadrenal function, is probably depressed after total pancreatectomy. Furthermore, minimal resection line which will not influence the normal function of pancreas is not agreeable, such 75%, 80% or 95% resection of the total pancreas in rat. So far, studies on the exocrine function other than endocrine function after partial pancreatectomy have been limited. Therefore, the main purpose of this study is to examine the changes of exocrine as well as endocrine function of pancreas at the different time interval after 60% or 80% pancreatectomy in rats. The results summerized as follow: 1) In both 60% and 80% resected groups, a slight decrease of the total body weight was observed at a day after partial pancreatectomy in rats, but the body weight was continued to increase for following 100 days. 2) The weight of residual pancreas was continuously increased during experiment in both 60% and 80% resected groups. But the content of tissue protein in residual pancreas was significantly decreased comparing with those of resected pancreas. 3) The flow rate of pancreatico-biliary juice was significantly decreased immediately after pancreatectomy in both resected groups. But it was recovered to control level after a day in 60% resected group, after 30 days in 80% resected group. 4) The output of amylase and lipase in resected groups were significantly decreased right after pancreatectomy comparing with control group. In the 60% resected group, the output of amylase was recovered during the following 100 days after pancreatectomy, while lipase output in 3 days. However, in the 80% resected group, the output of amylase and lipase were not recovered during 100 days after pancreatectomy. 5) In order to examine the endocrine function, blood sugar level were examined at all experimental periods after partial pancreatectomy. There was no difference between control and 60% resected group in the sugar level. But in the 80% resected group the level was significantly incresed immediately after pancreatectomy, and reached the highest level at 3 days. Then it was decreased to control level during the next 10 days after pancreatectomy. The above results showed that in 60% resected group little changes were observed on pancreatic function, but severe functional impairments were observed in 80% resected group. This results suggested that the endocrine function was recovered within a short period, although the exocrine function was not recovered for a long time after 80% pancreatectomy in rats.

An 18-year-old woman with annular pancreas and duodenal duplication presented with recurrent acute pancreatitis and underwent a resection of duodenal duplication. However, the patient experienced recurrent abdominal pain after resection. Abdominal computed tomography and magnetic resonance imaging showed a dilatation of the peripheral pancreatic duct and stenosis and malformation of both the Wirsung's and Santorini's duct due to multiple stones. The modified puestow procedure was performed. The main pancreatic ducts in the body and tail were opened, and the intrapancreatic common bile duct was preserved. A Roux-en-Y pancreatico-jejunostomy was performed for reconstructing the pancreaticobiliary system after removing the ductal protein plug. The patient experienced no abdominal pain, no significant elevation of the serum amylase and lipase levels, and no stone formation during the 2 years of follow-up. This procedure is considered to be beneficial for pediatric patients with chronic pancreatitis due to annular pancreas and duodenal duplication.

Nypa fruticans Wurmb. (NF) has been used as a folk remedy to treat inflammatory diseases in Asia. In this study, we aimed to investigate the protective effect of NF water extract on cerulein-induced acute pancreatitis (AP). To measure the protective effects of NF on AP, AP was induced via intraperitoneal injection of cerulein (50 ㎍/kg) hourly for 6 h in mice. NF water extract (100, 250, or 500 mg/kg) or saline was administrated to intraperitoneal injection 1 h before the first injection of cerulein. The mice were sacrificed at 6 h after the final injection of the cerulein. Pancreas, and blood sample were taken for further analysis. Administration of NF water extract inhibited the pancreatic injury, the elevation of pancreatic weight/ body weight ratio, and the elevation of serum digestive enzymes such as amylase and lipase during cerulein-induced AP in mice. Also, pancreas MPO activity, which represents neutrophil infiltration, was inhibited by administration of NF water extract. Taken together, administration of NF water extract reduces the severity of cerulein-induced AP, which suggests a clinical basis that NF could be a potential agent to prevent AP.

We performed this study to evaluate the potential clinical marker of urinary trypsinogen-2 together with amylase, lipase and urinary amylase creatinine clearance ratio (ACCR) for the diagnosis of acute pancreatitis in dogs. In the experiment on daily changing patterns of amylase, lipase and ACCR measurements in experimentally induced pancreatitis dogs, compared to values measured in pre-induction state, significant difference was seen in amylase until 5th day of induction, and for lipase significant difference was found during the 7th day of observation period (p < 0.05). No significant difference was found in ACCR for the study period (p > 0.05). On SDS-PAGE analysis of urine from experimentally induced pancreatitis dog, The 26kd band was markedly increased compared with that of normal state and that band was confirmed trypsinogen-2 using substrate interaction and isoelectric focusing assay after being eluted. When assessing the appearance of 26kd band on urine SDS-PAGE 87.1% (range: 50~100%) of experimentally induced pancreatitis dogs showed positive results, whereas no corresponding band was seen in dog without pancreatic disorders. With this result, determination of urinary trypsinogen-2 assay was found to have a high diagnostic value with a 70% of sensitivity and 100% of specificity as a routine test for pancreatitis, although the detection of trypsinogen-2 in urine can be varied on the progression stage of pancreatitis at the initial visit to animal clinic. We therefore suggest that the promising results in this study be used for the development of dipstick test for detecting acute pancreatitis in the future research.
